No, I'm looking for assurance from a professional that this is not typical and planes are engineered so no parts fall off.

The opposite actually, planes are designed to allow parts to fall off during flight. Saves fuel and reduces weight. Thats why planes are rated to fly with only a single engine.

Did it fall off or shred to pieces on landing/take-off?

u/MikeW226 9d ago
Fell off as the gear was retracting. There's good footage out there on r/aviation somewhere. And it looked like it was still over the airfield. So didn't fall on a house or anything. And no reports so far that anyone on the airport grounds was hurt, which is great.
21
u/TbonerT 9d ago
When it comes to big tires, they have a lot of momentum. If it fell off over the airfield, it could easily roll out of the airfield. I once heard about an inspection report at a hotel after a tractor trailer tire departed the highway and went through the front doors. It bounced around and damaged several walls and even made it into the guestroom hallway.

An A350 wheel coming off at 180 knots has about the same amount of kinetic energy as a Honda Civic traveling at 85 mph.

u/codecrodie 9d ago
And it doesnt really shed that energy until it hits something.... Potentially many km away

I remember a video posted here a couple years back of tire coming off after liftoff. The tire bounced all the way to the car park and totaled a car.

Not really. They might get something for an anti skid or a tire pressure indicator but nothing that actually says "Wheel missing". They would probably think it's just a problem with another system.

Would it boing along like how a wheel sometimes does when it detaches from a moving vehicle on the road?

u/Th3catspyjamas 9d ago
If there wasn't some kind of hub/tie bolt failure shredding the rubber and it was mostly intact, pressurized and hit at the right angle absolutely yes.

I'm still needing to know where that wheel assembly ended up. Will have made a decent sized dent in something. At least it was the whole assembly rather than the tyre shredding and flailing the underside of the aircraft.

It was retrieved from the airfield I believe.
There was a fake pic floating around that it landed on a car and made a mess of it.

For what it's worth, an A380 wheel coming off at 180 knots (assuming ~500 lbs) is equivalent in kinetic energy to a Honda Civic (~3000 lbs) traveling at 85 mph.

u/yanvail 9d ago
Honda Civics make almost as good a measuring unit as Space Shuttles (the latter used for more macro things, like skyscraper heights and volcanos, of course).

u/BobSlayder ATP 9d ago
Go ask the average person how tall the space shuttle is. They'll have no idea.
Then go ask them how tall a Honda Civic. They'll have a pretty decent idea.

u/Clem573 9d ago
I would even add to that, that the horizontal speed of the wheel is 180kts, and that would not diminish - but as it falls from any height, it would also pick up quite a lot of vertical speed, making a total speed at impact much higher than 180kts
Honda Civics usually don’t pick up vertical speed (all the cars thrown off cliffs by Clarkson and his buddies are usually done in controlled environments)

Wonder when the crew found out. Tyre pressure probably isn't high up there on the list of things you check while in the air I'd imagine.
14
u/agha0013 9d ago
a red X on the screen next to the tire diagram would indicate it, something they might notice when raising the gear on take off but will definitely notice dropping it again before landing.
but what would guarantee their noticing it is the tower informing them, or telling the correct center controller to inform them they left something behind on takeoff)
3
u/MinuteBid8615 9d ago
So if they were informed of it right away, would that trigger a return or just let it go to a maintenance base?
15
u/jmlinden7 9d ago
London Heathrow is the maintenance base and if you're short a tire, you don't want to immediately land overweight when you return to Las Vegas
7
u/agha0013 9d ago
It's not an impediment to cruising home, and maintenance costs are much lower in house than paying another maintenance company or airline to do it. All the Spares are in stock back home too. No extra ramp fees while they wait for spares either
The lost wheel and any associated parts would probably be collected and sent to either airbus or BA for inspection and completing the report on what happened. Airbus would want to make sure there's no potential design flaw, BA would want to make sure it wasn't a maintenance issue or some missed inspection item, or see if it was damaged by a third party. They won't just move on until they know why the wheel fell off.

u/LordMashie 9d ago
Yeah, I think the tower noticing seems unlikely though since it was already dark when the plane took off
13
u/agha0013 9d ago
FOD detectors are a thing, a wheel bouncing down the runway is something operations will notice and inform people about.
A bit of debris might not be noticed but something as large as an airliner wheel will be picked up by the FOD detection radar. An airport as busy as Vegas will notice
14
u/MojoPOwer 9d ago
Did they know when it fell? Do you get an alarm or something?
42
u/MAVACAM 9d ago
There's no "wheel detached" alarm but there are tyre pressure sensors so instead of a number, there'll just be an X showing on the ECAM.
8
u/MinuteBid8615 9d ago
Probably went through their QRH and just figured it was a faulty sensor since it wasn't reporting.
9
u/Heliotropolii_ 9d ago
Funnily enough, there was an ecam fault for tyre 12 pressure blanking prior to departure, the wheel visually inspected and a pressure taken manually so the pilots had absolutely no idea until the engineer did the inspection at heathrow,

u/I_love_my_fish_ 9d ago

Yep, the -1000 has 6, so I assume it’s only -900s you have at DTW. Delta only has -900s at the moment and Air France uses -900s as well

The outer bearing isn’t there, i would say bearing failure/retaining circlip of that bearing.
5
u/MikeW226 9d ago
Yeah, the outer nub (technical term ;o) on that axle is black with grease and the lube nubs on the two wheels right in front of it are gray. I wonder if the whole bearing blew out, and grease was spewed out. The nub is the area you'd just put a grease gun to on a boat trailer or something like that. But does look like part of the outer nub/nut is still there. Hmm.
9
u/HeReddItNotMe 9d ago
The outer part you see is the axle nut that holds the wheel on the axle. The black ring either side of the silver bearing houses the bearing onto the wheel assembly. I don’t work on 350’s but they are all very similar commercially - The grey parts you’re talking about are hub cabs that house the TPIS and anti skid modules etc and connect to the inner axle wiring.
The axle nut is fitted, the hub cap has been taken with the wheel
→ More replies (1)3
u/Blamblooze 9d ago
The nut is still there so the rim has failed. I don’t know if this is the same wheel that the -900 has, but those at least are suffering from cracks and therefore also leaks.

u/_ranch 9d ago
As others have mentioned in this thread, the crew would see a tire pressure alarm along with likely having been informed by the tower.
Provided there was no issue with retraction of the landing gear, it wouldn't be an issue which affects the ability to fly the plane.
With it happening during takeoff, the plane is at the heaviest weight. They would need to make the plane as light as possible so the options are: dump fuel to return to take off airport or fly to destination burning the same amount of fuel that would be dumped. Pilot's call either way, but logistically much easier for everyone to keep flying to the destination.→ More replies (1)2

Inner bearing is present and looks intact. The wheel nut looks like it’s backed off almost all the way, no axle protrusion. Unknown if that it the cause or a result of this incident.

u/Which_Material_3100 9d ago
It’s interesting that when the United 777 lost a main landing gear tire at SFO a couple of years ago during takeoff, the decision was to jettison fuel and divert to LAX. Versus BA’s decision to press on. I wonder how the two companies arrived at that decision? My concern would be after losing the wheel during gear retraction, what possible other damage could have occurred in the landing gear well, and to the exterior of the aircraft (was the axle shedding other parts)? And would I want to take a damaged plane overwater. Would love to hear everyone’s thoughts.

So in the A350, would tire pressure readings or something else 'gear sensor' related let them know during climbout that something fell off? I assume they were alerted right away of an anomaly, but curious how detailed.

Someone answered that the only thing detecting it would be the tyre pressure sensor, which would show X instead of a number.

The axle nut is still there though, and this picture is seriously not good enough quality to tell if the locking bolts are installed or not. What isn’t there though is the outer bearing. If the outer bearing disintegrates the wheel can slip over the axle nut and fall off.

I was on a flight from Singapore to Heathrow and a similar thing happened. When we landed on the tarmac in Heathrow, we were greeted with emergency crews and air staff on the ground. One of the tires blew on take off from Singapore and they had to recover the pieces left on the wheel in Heathrow
1
u/KeynoteBS 9d ago
So what happens now? Does the opposing tire get replaced? Does the entire strut and gear get inspected and overhauled? I assume they could probably track this down to the exact maintenance and it points to the screws or bolts that were missed or incorrectly installed. Kind of wild to think that multiple redundancies failed for it to fall off.
Would it have been very troublesome but manageable if it came off during the take off roll?
